16 TECHNICAL SCOPE TECHNICAL SCOPE SYMPOSIUM A - Magnetic and Superconducting Materials The symposium is intended to bring togheter scientists and engineers interested in all aspects of experimental and theoretical research in magnetic and superconducting materials, as well as in their technological applications. Contributions are expected in topics ranging from basic properties to recent developments in magnetism and superconductivity at nanoscale. Emphasis will be given on new materials, properties and devices. Participants are invited to submit abstracts related to the topics listed below. Contributions in other areas of magnetism and superconductivity will also be considered.

Non-degradable polymeric waste has become a global concern in terms of both cost and ethics. Biodegradable polymers offer alternatives for packaging that minimize environmental pollution at a relatively low cost. Applications of these polymers in the food and biomedical industries have been investigated. For packaging, polymeric materials should function as a barrier for water, oxygen and lipid transfer in food systems and, therefore, should contribute to the extension in the shelf-life of food. For medical applications, the material should repair tissue defects, and be designed to exhibit adequate physical and chemical properties and, at the same time, to enhance cell adhesion, proliferation and differentiation. Although nanostructured reinforced composites are highly recommended for bone implants over the micrometer sized composites for their improved reinforcement efficiency and biological responses, they may also pose toxicological effects. Current trends in polymer science also reflect the fact that synthesis and manufacturing of polymers should be done using environmentally friendly processes. All these aspects of polymer science and technology are hugely demanding in present times. Biodegradable polymer nanocomposites Materials for biodegradable packaging Scaffolds for tissue engineering Synthesis, processing and characterization of biodegradable polymers Toxicity and biodegradability of polymeric materials SYMPOSIUM C - Electronic Materials This Symposium will cover the fabrication and characterization of materials, interfaces, and devices ranging from advanced silicon technology to novel, unconventional systems.

The Symposium will provide an exciting environment for the discussion of recent theoretical and experimental developments in the general of materials that display unusual negative properties, such as negative thermal expansion, negative Poisson's ratio (auxetics), negative compressibility and negative refractive index (metamaterials). The first reports on materials exhibiting negative thermal expansion (NTE), i.e., contracting as temperature increases, go back more than 50 years. This property is not restricted to exotic classes of materials. Even familiar compounds such as hexagonal ice and water show NTE, although over a limited temperature range. The field has been growing since the re discovery of NTE in cubic ZrW2O8 (AM2O8 family) in Several other classes of open framework materials, including AO2, AMO5, AM2O7, A2O and A2M3O12 compositions, have emerged as potential sources of crystalline phases displaying low or NTE. These materials have opened up opportunities for the scientific 17

18 TECHNICAL SCOPE community to exploit negative thermal expansion for a variety of applications. Negative compressibility materials expand when submitted to isostatic pressure. The emergence of nano science in last 20 years has led to the development and engineering of novel materials and properties through the design of complex architectures with engineered sizes, compositions and morphologies. For example, by controlling the ratio of single wall to multi-wall carbon nanotubes in composites their Poisson's ratio can be tuned from positive to negative values, making possible a biaxial expansion under hydrostatic pressures. Recently, it was experimentally demonstrated, for a certain wavelength range, that it is possible to design materials and systems with negative refractive index (so-called metamaterials), opening a rich research field with many envisioned applications. The discovery of the materials with negative properties has stimulated the scientific community to pursue the development of models that both enable an understanding of the fundamental mechanisms responsible for these striking properties, and guide the development of novel materials, which could help overcome some of the technological challenges facing modern society. Negative thermal expansion materials Negative Poisson's ratio (auxetics) Negative compressibility Negative refractive index (metamaterials) SYMPOSIUM F - Nanostructured Functional Materials for Advanced Energy and Environmental Applications While fossil fuels presently provide worldwide over 80% of its energy needs, concerns about long term availability, cost, and emissions has stimulated great interest in identifying a) improved combustion cycles with reduced emissions utilizing catalysts and sensors, b) electrochemical conversion via fuel cells, c) capture of waste heat by thermoelectric devices, d) capture of solar energy via photovoltaic cells, e) storage of electricity via high energy batteries, f) solar assisted splitting of water to generate hydrogen, g) energy conservation via the use of smart electrochromic windows, and h) use of solid state lighting. In all of these active scientific and technological areas, nanostructured functional materials appear to be playing an ever increasing role. For example, nearly all recent advances in the areas of thermoelectric devices, dye sensitized solar cells and lithium batteries have resulted from the optimization and control of materials on the nanoscale. In this symposium, contributions are invited which describe work directed towards the science and technology of functional materials designed for advanced energy and environmental applications.

19 TECHNICAL SCOPE Application of Molecular Dynamics to materials SYMPOSIUM H - Structure-Properties Relationship of Advanced Metallic Materials Over the last decades, we have witnessed and benefited from the development of numerous new technological systems. The development of these technologies emphasizes the importance of materials as the primary building blocks for engineering developments. On the one hand, the properties of materials have dictated nearly every design and every useful application that the engineer could devise. On the other hand, with the present sophistication of science and engineering of materials, it is no longer simply a question of being satisfied to design with existing materials. We are now requiring new materials with new properties to fit our designs. This is true in all fields of engineering. This search for new materials with improved properties now occupies an important position in the engineering world. A number of procedures have been recently proposed to aid the development of materials science and engineering. For example, the advents of the scanning tunneling microscope and the atomic force microscope, together with developments in electron microscopy, have opened new ways for the study of structure materials at the nano-scale. Advances in the field of fracture mechanics and its application to structural design and material selection have helped to offset some of the potential dangers posed by increasing technological complexity, and have undoubtedly prevented a substantial number of structural failures. The development of thermo-mechanical processing in steel industry changed the traditional concept of deformation processing, when the single operation to reduce thickness and to provide a desirable shape has been improved to product specific microstructures, with which are associated particular mechanical and physical properties. This Symposium deals with these topics, to show some of the new most important scientific and technological advances in materials science and engineering. The objective of this Symposium is to discuss the relationships between processing, structure, properties and performance of advanced engineering metallic materials, with emphasis in new fabrication and characterization techniques. Techniques for microstructure and properties characterization; Fracture mechanics applied to structural integrity; Light alloys (Al, Mg, Ti) for automotive and aeronautical applications; Recent developments in steels for automotive industry and for gas/oil pipelines; Materials to resist creep. SYMPOSIUM I - Sol-gel route to prepare new inorganic, hybrid and multifunctional materials The progress in obtaining new inorganic, hybrid or multifunctional materials depends on the development of synthesis techniques that allow a structural control at atomic and molecular scale. The sol-gel method, although very old, remains one of the most efficient and versatile techniques for this type of control. This symposium will focus on recent progress in the development of inorganic and organo-inorganic hybrid materials via sol-gel method. These materials present a huge variety of properties and functions, with applications in areas such as optics, electronics, electrochemistry, catalysis, energy among others. Inorganic materials made of silica, alumina, titania, zirconia or other oxides Hybrid materials made of silica, alumina, titania, zirconia or other oxides Nanocomposites Polysilsesquioxane Porous materials as: zeolites, foams, microporous and mesoporous, hierarchically structured Alternative routes for sol-gel method (non aqueous reactions and others) Characterization techniques for materials obtained by sol-gel method Applications of sol-gel materials in: optics, sensors, catalysis, separation methods, electric materials, energy generation and storage, coatings, films and others SYMPOSIUM J - Solidification of metals and alloys 19

20 TECHNICAL SCOPE This proposal refers to a general symposium covering several topics in solidification science. Solidification is a multidisciplinary field of high importance for comprehension of industrial processing involving molten alloys such as welding, continuous casting, powder metallurgy and foundry. Process limits are still present and are to be overcome. Many groups in Brazil and abroad have carried out valuable research regarding to particular subjects like nucleation, macrostructure, structural transitions, as-cast microstructure, porosity, inverse segregation, metal/mold interface, interdendritic fluid flow, and mechanical properties of as-cast metals. All these topics have been studied following either experimental or modeling approaches, with remarkable complementary aspects between them. Nowadays, complementary research has been developed concerning the evaluation of experimental data from stationary and transient directionally solidified alloys. Dendritic and cellular growth Correlations between dendritic/cellular arrangement and mechanical properties Corrosion resistance of as-cast structures Zone melting Microsegregation and macrosegregation in binary and ternary alloys Porosity in binary and ternary aluminium alloys Modeling of heat and mass transfer during solidification Laser surface remelting (LSR) Eutectic and monotectic growth Bridgman technique Continuous casting Influence of convection on as-cast structures SYMPOSIUM K - Supramomolecular organic materials for electronic, photonics and nanotechnology This Symposium intends to bring together chemists, materials scientists, physicists, and engineers from both academia and industry to share information on the organic materials for emerging new electronic and photonic technologies. It includes all types of organic molecular and polymeric functional materials, their electronic and photonic properties and device applications. The research topics include all types of molecular, organic, and polymeric functional materials, their nanostructured composites and blends, their synthesis, processing and nanofabrication (molecular crystals, multilayers, self assemblies, ultrathin films), spectroscopic characterization, morphology, electronic and photonic properties. In addition, the symposium is equally opened for applications in organic devices as well in organic inorganic hybrid devices: organic light emitting diodes (OLEDs), organic fieldeffect transistors (OFETs), organic photovoltaics (OPVs), integrated circuits, non volatile memories, sensors & detectors, and single molecule electronics.
